#4 Maurizio Sarri breaks a 14-year old managerial record
It only took 12 fixtures for Maurizio Sarri to break into the Premier League record books as the best performing rookie manager in the English top flight.
Sarri overtook Frank Clark's record for the longest Premier League unbeaten run of a new manager, which he achieved with Nottingham Forest in 1994, when Chelsea extended their unbeaten run to 12 games with a draw at home with Everton.
Interestingly, his unbeaten streak included tricky fixtures against the likes of Arsenal, Manchester United and Liverpool.
Chelsea, at this moment are also the only side in Europe's top five divisions yet to lose in any competition, following Juventus' Champions League defeat against Manchester United in midweek.
Sarri boasts one of the best managerial start record of any manager, so the question is - Will that be enough for him to claim the league title this season? We'll have to wait and see.
